For Marine & Industrial Applications

WHAT WE DO:
Sims designs and manufactures cartridge style and spring loaded
type mechanical seals for ALL centrifugal pumps. Sims seals are unique because they incorporate SIMSITE® structural composite glands and SIMSITE® structural composite sleeves for superior corrosion resistance.

HOW WE DO IT:
The glands have an O-ring design for sealing against the casing, which enables the SIMSITE® seals to be used on rougher surfaces or split case pumps. The seal faces can be traditional, or silicon carbide against silicon carbide or diamond faced for longer life and better operation


ALL MECHANICAL SEALS ARE DYNAMICALLY TESTED IN THE FACTORY PRIOR TO DELIVERY

HYDRAULIC BALANCE:
SIMSITE® parts are manufactured with precision machining, which provides a product with no casting imperfections. By manufacturing our products in SIMSITE®, our parts will not corrode and therefore will not go into an imbalance, and will not support electrolysis, or stress crack corrosion.

In a SIMSITE® cartridge-style mechanical seal, the seal faces and the spring tension are pre-set. The cartridge-style mechanical seal is simply bolted to the seal chamber. The springs are isolated from the fluid.

Are isolated from the fluid.
SIMSITE® Cartridge Mechanical Seals come standard with SIMSITE® Structural Composite Sleeves, which are corrosion & electrolysis resistant and will protect the shaft, and prevent galvanic corrosion.  


All SIMSITE® mechanical seals for the US Navy
are shock and vibration qualified.
